I need some help to dump some multicarts

[NakamangaHikari]

Recently i got this 2 multicarts, but i'm having some problems trying to dump the ROMs due to some issues with my mapper scripts.

The carts that i got are:

7-in-1 (VT8008) - It uses mapper 45
I tried it to dump, but i only got a glitchy menu with not working games:

6-in-1 (BCD290) - It uses mapper 52
I don't have the mapper script, the only thing that i managed to dump it's menu and the Super Donkey Kong game that has:

The dumper that i'm currently using it's the FC Dumper V 3.5 by Tengu, the mapper scripts are in .nut format.

i have to say that i only have a basic and superficial knodledge about what a mapper is and how it works, i'm just an entusiast that wants to preserve and share the cartridges that i have in my collection.
Thank you for hearing and my best regards, any type of help will be welcome.

I fixed the problem with the 7-in-1 cart, here's the working rom.
Still, i need a mapper 52 script for the other one.
